Hey guys,

appreciate the work that you are doing, keep it up!
I can't login if my passwords contains a "%" character, here is the log(ish):

File "/usr/lib/python3.6/configparser.py", line 402, in before_set
"position %d" % (value, tmp_value.find('%')))
ValueError: invalid interpolation syntax in 'xxxxx%xxxx' at position xx

Best Regards,

Is it possible to download the DuinoCoin blockchain for inspection and verification?

This is a vital part of building trust into the system, that anyone can verify its integrity.

Hi! I'm a little bit new to Duino Coin, I have to say I am very interested on this project and hope it gets bigger with time. Maybe we can see DUCO on Binance soon!

So the first thing I wanted to do was to try to mine with the ESP32 and found some issues with the code that I think could be improved. Maybe there is a reason to why it was implemented the way it is right now that's why I'm writing it first here. I will list some of them with some suggestions on what can be done:

• The tasks:
  From what I know about RTOS is that you don't usually want to kill the tasks unless is very very necessary and it is done rarely, in lines 188 and 108 the tasks kill themselves. Since right now the server is requesting a reconnection frequently the tasks will be killing themselves a lot of times. What I think should be done is to wrap everything inside the task on an infinite loop with a "for(;;)", I have test this without any problems whatsoever.

• The variables, arrays and pointers:
  When we program on microcontrollers we have to think about the limited memory (even for the ESP32). So declaring the same variable or array multiple times could be asking for problems in the future. Some people could say that maybe the compiler can resolve this but trusting on the compiler to do something that you aren't really sure if he is gonna do is not a good decision. Even worse if you are reserving memory every time for an array or pointer, this can become on a memory problem, if you don't free the allocation the memory will become full and even if you use "free" to deallocate the memory it will become fragmented and would become a major problem on long runs. What should be done is to declare all variables once, they can be declared globally or locally inside the task, but outside the infinite loop. The memory allocation too, but there is something else that can be improved, in lines 84 and 162 instead of using a constant pointer (which is not really constant since it could change on every hash calculation, I'm not really sure what happens here or how the Arduino or the compiler handles this but it seems to workout somehow) you can use ".c_str()" directly so it would become something like this:
  "esp_sha(SHA1, (const unsigned char*)hash11.c_str(), payloadLenght1, shaResult1);"
  I have tested it without any problems and with this you are not messing with pointers directly anymore, the Arduino does it on the background for you.
  https://arduino.stackexchange.com/questions/682/is-using-malloc-and-free-a-really-bad-idea-on-arduino

• The esp_sha function:
  I can understand why you just use the esp_sha function in one of the tasks, the tasks could call this at the same time. I think the RTOS or the processors can handle this without problems. Right now I am using the esp_sha function on both tasks without problems, I think it is even faster than before. This is a suggestion that should be tested more since I don't have a strong argument on why it works like that.

• The WiFiClient buffer and reconnection:
  I'm not really sure why but the server seems to close the connections to the ESP32 (maybe this is not only related to the ESP32 but I didn't try another miner) very frequently and this is causing other problems on the code too. The first thing I realized about the client handling is that the code is not waiting enough time to receive the response from the server, it sends a request and right after this it tries to read the buffer. I'm not sure if this is handled by the library or on hardware or if it just isn't handled at all, I just think that is a good practice to wait for a response from the server, since you are the one that are starting the transaction. So what I'm doing is to put this portion of code after lines 59 and 132:

    while(!client1.available()){
      if (!client1.connected())
        break;
      delay(10);
    }
    yield();
    if (!client1.connected())
      break;
    delay(100);
    yield();
    int buff1size = client1.available();
    Serial.print("CORE1 Buffer size is ");
    Serial.println(buff1size);
    if (buff1size<=10) {
      Serial.println("CORE1 Buffer size is too small. Requesting another job.");
      continue;
    }

So there is something more on this code, besides waiting for the response on the while loop it is breaking the upper while if the connection is lost so it can connect again. In addition to this I am adding some "yield()" functions to manage the WiFi connection after potentially long loops or waiting times. And at the end I am validating the buffer size to be more than 10 bytes, if it isn't it returns to the beginning of the upper while.
There is other time that the client posts something to the server and it is when it finds a result, in this case I do it differently, here is the code I did that goes before the lines 92 and 172:

        if (!client1.connected()) {
          Serial.println("CORE1 Lost connection. Trying to reconnect");
          if (!client1.connect(host, port)) {
            Serial.println("CORE1 connection failed");
            break;
          }
          Serial.println("CORE1 Reconnection successful.");
        }

And here is the code after lines 92 and 172:

        Serial.println("CORE1 Posting result and waiting for feedback.");
        while(!client1.available()){
          if (!client1.connected()) {
            Serial.println("CORE1 Lost connection. Didn't receive feedback.");
            break;
          }
          delay(10);
          yield();
        }
        delay(100);
        yield();

The code that goes before is for trying to reconnect if it lost the connection, I do this because if it finds a solution it should post it so it should try at least one reconnection before going out of the loop. If the reconnection is not successful then it leaves the loop. For the next part of the code it waits for a response from the server like before. As I'm writing this there could be a problem with this approach, since the server sends the version of the miner immediately after connecting it could be mistaken for a feedback response. Maybe I can work this around later, but it is better like this even if it is mistaken.

Finally I have been playing with the timeout value for the clients, right now it is 1 second and it is working fine besides the reconnections from the server. Another thing I did was putting more yield() functions here and there, where there is a potentially long waiting time.

Oh another suggestion that can improve even more the code is not using the String class. I know it is convenient sometimes but is very messy and I think it uses more memory than it should use, if we use just char arrays or pointers I think it could improve the code and we can even be closer to porting the code to another platform different than the Arduino.

One last suggestion is to add a WiFi reconnection task, I have been dealing with a poor WiFi connection at home and it's been a pain.

I'm sorry for the long post but I wanted to to detail everything I could about the things I have been improving. Please let me know if something I'm doing is wrong or if I need to change something else. Thank you!

Wallet gives me a script error, windows install window just vanishes and doesnt do anything.

Windows 10 fully updated

Pool workers: -217

That's not expected :D

Hi Comunity,

i tried to run duino-coin on a RPI3 without success.
It says you don'T need python anymore but with the command: ./PC-Miner i get the following massage.
-bash: ./PC_Miner: Permission denied

So i gave permisson to the directory and files and got a new Massage.

-bash: ./PC_Miner: cannot execute binary file: Exec format error

Any Idea?

Hi there! Seems I'm the only miner @ official pool for now (ofc, together with revox)

Sometimes there're some issues with pool, so there is no ability to receive balance or mining "jobs".

I've added job logging right here:

job = soc.recv(1024).decode() # Get work from pool
print(job)

So I see there is no job received sometimes (minig stops), but the miner does not try to reconnect, it tries to receive from socket.

Thank.

P.S. Interestiong project :-) I'm not on Python side btw, but may take a look into adding .NET miner :-)

Are you interested in adding Discord server for this project?

Attempting to run the wallet setup both on linux, pc and they both freeze up. I have to force quit it each time. It allows me to create user name and password but locks on the register button. Will try on another computer in a bit but wanted to see if this was common one is a windows 7 pc and the other is a raspi 4 with buster on it (which I would prefer to get working).

Greetings,

first of all: thank you for the coin I was always waiting for. Great job!

I tried to open Wallet.exe in Windows 10 and Wallet on the newest stable NixOS, but neither do seem to work on their respective target systems. Since these are release builds, the exceptions disappear quickly and nothing is really said, besides that a file cannot be found.

I did not find any dependency requirement for the pre-built binaries, so I expect them to work out of the box.

Are there dependencies missing or are the builds not working for different reasons?

Thank you.

how can i contribute i have smth ready

In readme is stated that server will send version number 1.6, however server sends 1.5.

The registration page for creating a wallet account appears to be having a problem.
I have tried several different user names and a variety of passwords to create a wallet account.
I have also tried mixed case, all lower case, mixed case with special characters.
I went to the link https://wallet.duinocoin.com/ which then redirects to a non-ssl link.
After clicking the register button, I only see a "Proxy server online" message at the bottom of the window after a few seconds.
unable to create an account at this point.

When I try to start PC_Miner on debian buster it says Error loading Python lib '/tmp/_MEIBa354u/libpython3.8.so.1.0': dlopen: /lib/x86_64-linux-gnu/libm.so.6: version `GLIBC_2.29' not found (required by /tmp/_MEIBa354u/libpython3.8.so.1.0)

Hi,

web wallet shows "no miners detected".
Should this show my named rigs and their hash rates?

Best,
Endre

It would be nice if you could add a todo list (I think github has a feature called "projects") so that contributors or people that want to contribute will be able to see what they can work on.
Thank you

Hello @revoxhere

I decided to create a library to make the Arduino code more clear and easy to maintain.

• https://github.com/ricaun/arduino-DuinoCoin

The current version only works with Arduino_Code V2.4

The idea is to add the ESP8266, ESP32, and other microcontrollers in one library to make the ducos1a more simple.

See yaa!

How transfer duco to another wallet??

Mixed content detected by Chrome, and it will block it, I think someone may need to modify it.

may the cdn link.

When you send funds to someone successfully, server responds with "Successfully transfered funds!" however, there is a typo in that sentence, the correct sentence is: "Successfully transferred funds!".

I have download visual studios tools C++ but the issue persist

To make Duino Coin a real open source project, it would be necessary to also open source the server and API software. Maybe I missed it, but it doesn't seem to be available anywhere.

This would also answer #321 and make #320 easier as people could help.

Really nice project BTW!

While running AVR_Miner.py on Linux node connected to Arduino UNO. Has been working fine until today.

I wonder how the Kolka system works.

Apart from the information that it seems to be a town in Latvia and this image this doesn't seem to be documented anywhere.

How does it work? What's the exact formula behind it to calculate the reward?

When rasp connect to Arduino, programm try to start mining thread, but programm reboots.

Alpha 3 wallet crashes if i execute miner and vs versa ( Windows

Rewards lost from mining with previous pre release

About community contributions: can you please add any documentation on how to make it work ?

About supply, block rewards and all the stats? where can i find it ?

Thank you in advance

Hi,

I prepared several machines to mine and I have been doing so for a few days.
No matter which algorithm I use or what type the machine it is, all of them lose connection at one point and stop mining.
No machine was able to mine for longer than 8 hours without me having to restart the miner.
I start mining on all machines, go to sleep, and in the morning none of them mine because they lost connection at one point.
I can solve this for myself using a combination of ssh, screen and crontab, in order to restart the Miners every hour.
However, it would be nice to have a more robust reconnection procedure that is inbuilt.
Does anybody else have this issue?

Best,
Endre

There are services like https://originstamp.com or https://opentimestamps.org/ that offer blockchain timestamping (basically putting a hash of a file into one or more blockchains as a matter of proving the file existed at a certain time).

Pretty much all of these services have one big problem: They can only timestamp documents so fast. For example, the fastest OriginStamp can do using Aion is 10 minutes. OpenTimestamps is around 10 hours AFAIK.

With DuinoCoins instant transactions, this would be a huge advantage and would make bulk timestamping of rather fast things (like git commits for example) viable.

The only thing the blockchain needs to provide is a means of putting some information into a transaction. With Bitcoin, that information can be a recieving address generated from the hash of the file(s) to timestamp.

Would that work with DuinoCoin? Is it possible to somehow ”attach” information to a transaction? Or is everything just username-based? There are certainly hashes involved, but is it possible to control that hash to some degree?

This would be a super awesome usecase for DuinoCoin!

Then I tried redownload it and starting again now getting

Hello, i have a 1.8 tft spi oled display(128x160) st7735. Is it possible to show my hashrate of all miners and my balance?
Thanks!

PC Wallet does not show ESTIMATED PROFIT sometime.

Not sure if this is cause I'm running on a Mac, Ill try later on a Linux but just wanted to get that out there just in case it is a problem. I'm running Version 1.1.

I'll post updates if it works on Linux. I'm sure it will though.

Not sure whats going on there I do have some Arduino's mining and a raspberry pi for fun but certainly not that many devices all is good but just noticed the workers keep creeping up for me. Not sure if a issue but thought I would let you know.

Hi,
yesterday I started up 5 ESP as miners which I had lying around. Today I noticed almost none was mining anymore, only one. In the api overview page I can see only one miner connected. If I connect a second one I receive the error TOO MANY CONNECTIONS which is either caused by Server.py#L979 or Server.py#L988.

To me it seems that hanging clients or not properly disconnected clients are not removed from the internal counter (code Server.py#L2418:L2432.

Maybe some similar code to https://github.com/revoxhere/duino-coin/blob/useful-tools/Server.py#L2436 is required to do a final cleanup or check in intervals if no user data exists anymore e.g. COUNT( minerapi[x]["User"] == "foo" ) == 0 (dummy code).

Even restarting my router to force a IP refresh did no help. Therefore I assume the code at Server.py#L2426:L2432 is not finaly triggered and results in workers[username] > 0 for zero actual connected clients.

I also tried to connect to Discord to see if anyone else has that issue, but it shows me some weird french error message 🤷‍♂️:

Hi,
I installed the latest version on a ESP8266 and ESP32 and both have trouble to connect to the backend server. Is it down at the moment?

it's a cool project, some suggestions:

1. domain ext from com to io or org;
2. push main site and wallet site frontend codes and i18n package to github;
3. avoid to use uncommon words on any UI.

Hi,

Nice project, this Duino-Coin. 👏

However, I wonder why the server and API over at http://51.15.127.80/ is unencrypted and doesn't use HTTPS? 🔐

This is the only thing that makes using Duino-Coin rather uncomfortable. 😕

Apart from Arduinos, all other devices (ESPs, Raspberry Pis and Desktops of course) support HTTPS. But Arduinos don't connect to the server directly, so that shouldn't be a problem.

So why is the server not encrypted? 🤷 (no offense, I'm just curious)

Cheers,

Yann

Hi,
When will the server be back online?

Thank you
